x264 HD Encoding

x264 HD Encoding

Simply put, it is a reproducible measure of how fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It's nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other.

Benchmark Results: The AMD Phenom X4 975 BE and 840 perform fairly well by beating out some of the lower end, but higher-priced Intel CPUs while closing in on some of the mid-range Sandy Bridge processors.
